KUALA LUMPUR, Oct 12 — Air quality deteriorated significantly across Malaysia on Friday, with 23 of the country's 68 monitoring stations registering 'unhealthy' air pollution index (API) levels during the afternoon period.

The widespread degradation in air quality affected numerous locations nationwide, prompting environmental officials to monitor the situation closely. The unhealthy readings indicate that sensitive groups, including children, the elderly, and those with respiratory conditions, may experience health effects from prolonged exposure to current air conditions.

Authorities have not disclosed specific locations most severely affected, though the distribution across multiple stations suggests the poor air quality is not confined to a single region. The Department of Environment has maintained its monitoring protocols to track any further deterioration.

Malaysia regularly experiences seasonal air quality fluctuations, often influenced by regional factors and local emission sources. Residents in affected areas are advised to check real-time API data and take appropriate precautions, including limiting outdoor activities and using air purification measures where necessary.

The situation remains under observation as officials continue to assess atmospheric conditions and their potential trajectory in the coming days.
